HENRY H. BROWN, OF WASHINGTON COURT-HOUSE, OHIO, ASSIGNOR TO THE WONDER MANUFACTURING COMPANY, OF WASHINGTON COURT- HOUSE, OHIO, A CORPORATION OF OHIO.

SPECIFICATION forming part of Letters l'atent No. 755,105, dated AMarch 22, 1904.

Application filed May 22, 1903.

To @ZZ whom it may concern:

ABe it known that I, HENRY'H. BROWN, acitizen of the United States, residing at Washington Court-House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My invention relates to gas-stoves.

The object of my invention is to provide a ro simple and eiicient construction consisting of few parts .that can be easily and economically made and assembled, the arrangement being such as to afford perfect combustion, and a maximum of radiating-surface, with means to limit the esc-ape of heat through the chimney/ and reduce this loss to a minimum. 'd My invention consists of the constru tions and combinations hereinafter describev ,and set forth in the claims.

ID the accompanying drawings, which orm a part of this specification, Figure 1 is a ectional view of a gas-stove embodying my 'ny ventiom Fig. 2 is a plan of the base with v the burner partly broken away to show inl t to the burner-conduit. Fig. 3 is a sectional view of same, showing-the burner above its normal position. Fig. 4 is a detail showing the burner bolted in position; and Fig. 5 is a plan of the stove, taken from above the upper A baffle-plate.

Like parts are represented by similarl letters of reference in the several views.

The base of the stove I have shown consists of radial arms a, with rings c', a2, a3, and a4 thereon. The ring a has supporting-legs a5, and the ring 1,2 is of suitable width for a groove or channel a in its upper surface, having an inlet 0,7 from a gas-conduit as, to the screw-threaded outer end of which the gas 40 connection i's made.

The several parts may be made separately and secured together; but I preferably form the same in a single casting and have so arranged the parts that this can be done, thus giving an economical construction.

An u pwardly-extending projection a forms a groove in which the lower end of the outer shell am of the stove rests in contact with the Serial No. 158,218. (No model.)

ring a', and the inner and outer walls of the lire-chamber rest on the radial arms c, the inner wall au in contact with the ring a* and the outer wall am in contact-with the ring a2, the arrangement of the rings being such as to stay the walls in position. VA burner consisting of a ring portion als, with a plurality of perforated upwardly-extending and preff erably cone-shaped lugs a, is provided with a groove on its under side, adapted to t over the groove in the ring (fand form a conduit, through which tlie.,gas passes to the perforated lugs. The burner is secured to the base by bolts 6015. A Y ,//In'constructing the top of the stove I have provideda cover for the {ire-chamber and a ring portion b', resting on the outer shell, to support the top cover b2 of the stove. The parts b and 'I connect `by arms b3, and I preferably cast saidparts in one piece. The ring portion b is provided with a suitable Vflange torest on the upper edge of the outer shell of the stove and also engage the outer surface of said shell. The cover I) is provided with downwardly-projecting iianges to contact and stay the walls tu and 412 in position. Bolts b4, extending through the arms c of the base and the arms 3 of the top, securely bind the stove together. A pipe b5 leads from the fire-chamber to vthe chimney. For the purpose of reducing the escape of heat into the chimney to a minimum, and

thereby increase, the heating capacity of the stove, I provide one or more partitions or baiiie-plates b in the fire-chamber, having perforations bl therein. Three such plates are preferably used, the perforations in the several plates varying in number and position to change thecurrent from one side to the other of the fire-chamber. The position and number of these perforations is best shown in Fig. 5, two ofthe perforations being in the upper plate on the side of the stove opposite to the escape-pipe b5. There are three perforations in the neXt or middle plate, and these arev represented by dot-and-dash lines in said figure. In the lowest plate there are iive perforations represented by dotted lines. Re-

ferring to the arrows in Fig. 1, it will be seen the current is guided from one side of the fire-box to the other until it escapes into the stack, and the perforations are reduced in number from five in the lower plate to two in the upper plate.

It will be seen I have provided a construction such that the top and base may each be cast in one piece, the latter including the lower half of the burner, so the stove can be easily and quickly assembled and secured together by bolts running from top to base. The central air-shaft and air-space about the lire-chamber gives a maximum of radiation, and the partitions or barile-plates prevent loss of heat into the chimney. An opening b in the gas-conduit admits air to said conduit, and it will also be seen that the burner is so placed that there is an opening on each side thereof through the base, which, together with the separate upwardly-projecting perforated lugs, affords an ample supply of air to each burner to give perfect combustion. Perforations 7) in the shell give access to the firechamber to light the gas.

The heat-currents inthe lire-chamber and the air-currents in the air-passages are shown by arrows in Fig. 1.

Having thus described lny invention, I claim- 1. In a stove such as described, the combination with the side walls of the lire-chamber, of a series of partitions in said chamber between the burners and outlet for said chamber, having perforations therein, each succeeding partition from said burners having a less number of said perforations so disposed as to guide the heat-currents from one side to the other of said chamber, substantially as specified.

2. In a stove such as described, a baseV consisting of radial arms with a plurality of rings thereon leaving openings on each side thereof, one of said rings having a channel formed on the upper surface thereof and acasing forming a conduit opening into said channel, all cast integrally, substantially as specified.

3. In a stove such as described, a base consisting of radial arms with a plurality of rings thereon leaving openings on each side thereof, one of said rings having a channel formed therein and a casing forming a conduit opening into said channel, all cast integrally, said channeled ring forming one portion of a burner, another channeled ring forming the other portion having a plurality of perforations therein, and means to secure said portions together, substantially as specified.

4. In a stove such as described, a base consisting of radial arms with a plurality of rings thereon leaving openings on each side thereof, supporting-legs, one of said rings having a channel formed on the upper surface thereof and a casing forming a conduit opening into said channel, all cast integrally, said channeled ring forming one portion of a burner, another channeled ring forming the other portion and having a plurality of upwardly-extending projections with perforations extending into said channeLand means to secure said portions together, substantially as specified.

5. In a stove such as described, the combination with three shells forming side walls of a fire-chamber, a central air-shaft and an airspace about the outer walls of said chamber, a series of partitions in said chamber having perforations therein, each succeeding partition from the lowest having a less number of said perforations so disposed as to guide the heat-currents from one side to the other of said chamber, of a base consisting of radial arms with a plurality of rings thereon leaving open spaces on 4each side thereof, one of said rings having a channel formed on the upper side thereof, and a casing forming a conduitopening into said channel cast integrally, said channeled ring forming one portion of a burner, another channeled ring forming the other portion and having a plurality of upwardly-extending cone-shaped projections with perforations extending into said channel, and means to secure said portions together, a top consisting of a circular portion having arcentral opening therein, a ring outside of said portion and arms connecting said portion and ring, said portion and ring having laterally, projecting anges, all cast integrally, and means extending from said top to said base to bind and secure the parts together, substantially as specified.

In testimony whereof I have hereunto set my hand this 19th day of May, A. D. 1903.
